Do squares exist in nature, or are the only square things man-made?

Answer 1

Hi. Some crystals are square such as iron pyrite. : http://www.answers.com/main/ntquery?s=iron%20pyrite&gwp=16

Answer 2

Not only are there squares made by nature, but I submit to you that there's virtually nothing man-made that is exactly square (cube, actually, since a square is a two-dimensional figure). Most anything manmade will have inconsistencies of some sort.

Answer 3

A square is two dimensional, so a physical object does not exist, no. There are cubes-due to the chemical bonds, salt crystals are cubic.

And technically, a point is infinitely small. Since men are incapable of measuring something to an infinite decimal place, men are incapable of producing a perfect square. It is a theoretical object in Euclidean geometry.

Answer 4

I beleive squares are only 2 dimensional but most things in nature would be 3 dimensional. In the field of metallurgy, many of the structures form cubes, or many cubes put together. the atoms arrange themselves as face centered cubes or body centered cubes.

Bismuth crystals are square/cubical
